About This Trial
Clinical Trial
The goal of this clinical trial is to evaluate the effectiveness of two types of Diverse Segments Defocus Optimization (D.S.D.O.) spectacle lenses in slowing myopia progression in children. It will also assess the safety of these lenses. The main questions it aims to answer are:
Do D.S.D.O. lenses reduce the progression of myopia as measured by changes in cycloplegic refraction an…
